[Objective] To determine the distribution and infection of HPV in cervical cancer and precancerous lesions. [Methods]Four hundred patients with abnormal cytology were examined by colposcopy. HPV diagnosis was done by polymerase chain reaction using MY09/MY11 primers, for genotyping blot hybridization was used. The pathological results confirmed standards. [Result]A total of 294 women were HPV-DNA positive. HPV-16 was found in 36.7％ of all women with positive HPV-DNA,HPV58 in 22. 1％, HPV-18 in 18.7％ and HPV-52 in 16. 0％. The infection of HPV in lesions with cervicitis, CIN Ⅰ , CIN Ⅱ and CIN Ⅲ were 55.6 ％, 69 ％, 82.7 ％ and 88.9％, respectively. HPV-16,-58,-18 and -52 were found in different cervical lesions. [Conclusions] The finding of HPV-58 and -52 expects HPV-16 and -18 among Huzhou women with CIN Ⅱ and CIN Ⅲ , and has important implications for the development of type-common HPV vaccines.%[目的]了解阴道镜检查患者的宫颈活检组织中HPV的感染率和亚型分布.[方法]对宫颈脱落细胞学异常的患者450例进行阴道镜下定位活检.活检组织同时行HPV基因分型和病理诊断,HPV基因分型采用斑点杂交方法进行.[结果]在450例宫颈活检患者中,其HPV感染率为65.3%.在HPV-DNA阳性患者中,检出率最高的HPV-16占36.7%,依次HPV-58为22.1%,HPV-18为18.7%,HPV-52为16.0%.在宫颈炎、CIN Ⅰ、CIN 、Ⅱ、D,CIN Ⅲ中HPV-DNA阳性率分别为55.6%、69%、82.7%和88.9%.在宫颈炎、CIN Ⅰ、CIN Ⅱ、CIN Ⅲ组织中均检测到HPV-16、-58、-18和-52.[结论]本研究中的宫颈活检组织中不仅检测到HPV-16和-18,还检测到HPV-58和-52感染,后者的发现为开发宫颈癌多价复合型疫苗提供了事实依据.
